2 Claims. (Cl. 297218) This invention relates generally to furniture,and more particularly relates to furniture having an upholsterycover'which may be readily removed or replaced. This application is adivision of my previously filed application, Ser. N0. 145,359, filedOctober 16, 1961, entitled, Removable Upholstery Cover for Furniture,and now Patent No. 3,188,137.

Most furniture in use today has the type of construction in which anupholstered seat, a back rest, and sometimes cushions and arm rests aresupported on a frame and covered by fixed upholstery covers. This fixedconstruction has required that cover material be drawn around andsecured to the frame by tacks or nails, and that separate pieces bejoined together in particular ways. Such steps must be taken in orderfor the furniture to maintain its resiliency and softness, while at thesame time the external fabric remains taut and neat in appearancethrough long periods of wear. This construction is so widespread that itis virtually accepted as necessary, and little thought is given to itsdisadvantages.

These disadvantages include the fact that a skilled upholsterer isneeded for the original construction in order for the furniture to havea finished appearance, good physical strength and also the externalsmoothness which is evidenced by a skin-tight and well-aligned externalfabric. In addition, the upholstery cover used today is almostinvariably not washable, but must be dry cleaned and can only be removedfor this purpose by a specialist such as an experienced upholsterer.Otherwise the furniture must be cleaned by special machinery andchemicals, without being removed.

Since the advent of foam rubber, polyfoam and similar integral materialsfor the cushioning of upholstered furniture, the fabric or cover is nolonger required to retain the cushion underneath the fabric as was thecase with the kapok, horse mane, hog hair and cotton felt which havebeen used heretofore.

From the standpoint of use and flexibility, upholstered furniture alsoleaves much to be desired. It has become accepted, for example, that thefurnishings in a room must be selected to be matching colors andtextures, and that changes cannot be made, barring great expense, exceptat lengthy intervals. As a necessary concomitant of the fact that drycleanable fabrics alone are used, unsightly marks of wear, burns, greaseand spots require that the entire set of furniture be sent out forrepairs or that the set be replaced. Clearly, where the furniture issubject to use by a great many people or by children who are oftencareless or destructive, higher quality upholstered furniture proveseconomically impractical. Attempts have been made to substitute othertypes of furniture but these often suffer so much in appearance and incomfort in comparison to the upholstered types that they must beregarded as strictly utilitarian items.

Freedom from the necessity to use the permanent upholstery type ofconstruction would greatly benefit those who must furnish hotels,motels, apartments and the like in a number of other respects. Thepossibility to change upholstery fabric at will to provide differentquality, texture or color fabrics is extremely desirable, particularlyif this can be accomplished at low cost. Great advan- 3,3114% PatentedMar. 28, 1967 tages can be obtained in merchandising furniture if theupholstery cover or fabric can be periodically removed and exchanged orwashed, much in the manner of bed linen. Furthermore, the possibility ofreplacing part orall of the upholstery cover of a given piece offurniture can be very advantageous, particularly if this can beaccomplished without the use of skilled labor and without retiring thefurniture from use for extended periods of time.

These basic problems are not solved by the use of slip covers over theoriginal upholstery cover of the furniture. In order to present aninitially neat appearance, slip covers are usually made to measure byskilled labor at considerable expense. Hardly ever, however, do slipcovers maintain a smooth and aligned appearance over a period of use,particularly at the back and arm rests of an item of furniture. Manyslip covers are just loosely attached to the upholstered furniture andare tied together by tie cords, slide fasteners or Zippers and the like.However, in this manner the fabric is tied to itself and cannot besecured to the furniture, and therefore cannot be kept straight.

It is accordingly an object of the present invention to provide a noveltype of furniture construction and upholstery cover in which thedisadvantages of permanent upholstered furniture are overcome.

Another object of the invention is to provide an improved type offurniture in which the upholstery fabric may readily be installed,without utilizing skilled labor, to give a finished appearance but maynevertheless be easily removed for cleaning or replacement.

A further object of the invention is to provide an improved type offurniture construction in which replaceable, washable fabrics may beemployed.

Still another object of the invention is to provide an upholsteredfurniture construction in which structural elements as well as thefabric may be removed, replaced or interchanged.

In accordance with the present invention there is provided anupholstered article of furniture comprising a frame and cushioningmaterial supported by the frame and forming a seat and, if desired, aback rest or arm rest. The cushioning material preferably consists oflatex foam rubber, polyfoam or the like material which is of integralsingle-piece construction and will not fall apart when the fabric isremoved. A single upholstery cover may be provided for the principalpart of the furniture so as to extend over the cushioning material, withmarginal portions disposed adjacent the frame. Elastic means such aslooped bands are secured along the edges of the marginal portions, andmeans are disposed on the .frame for engaging the elastic means. In thismanner the upholstery cover is secured to the frame and is stretched andmaintained tight over the cushioning material. As a result theupholstery cover may readily be removed for cleaning or replacement.

Furniture in accordance with the invention has exceptional versatilityin construction and use. Replaceable fabric arm covers, elasticallycoupled to the frame, may be disposed so as to give a tight andpermanent appearance without being sewn to the back and seat cover. Armrests of entirely different external styles as well as internalconstructions may also be used, in many instances interchangeably withthe same basic furniture unit. Cushions may be used as a part of thedesign or as optional items. The furniture may take the form of chairsor convertible beds, as well as sofas or couches. A significant featureis that constructions in accordance with the invention are amenable toall types of furniture design, including traditional, modern,contemporary and many others.

These and other objects of the present invention will become moreapparent from the following description, taken in connection with theaccompanying drawings, in which like elements are designated by the samereference characters, and in which:

FIG. 1 is a view in perspective of a sofa or couch in accordance withthe present invention, parts being broken away to illustrate itsconstruction, and one of the arm rest covers being shown removed;

FIG. 15 is a top plan of a portion of the davenport shown in theposition of FIG. 13; and

FIG. 16 is a top plan view of a portion of the davenport shown in theposition of FIG. 12.

Referring now to the drawings, and particularly to FIGS. 1-3, there isillustrated a sofa or couch embodying the present invention. The sofaincludes a frame generally indicated at 10 which may consist of wood, asis conventional, and which has a lower portion 11 forming an openrectangle. The frame 10 further includes an intermediate portion 12supporting the cushioning material 14 forming the seat and an upstandingrear portion 15 for supporting the cushioning material 16 forming theback rest of the sofa. The arm rest may be formed by a frameworkincluding a vertical front portion 17, a horizontal portion 18 formingthe arm rest, an internal cross bar 19 which is parallel to the armrest, an inclined portion 20 designed to be flush with the back rest 16and an upper horizontal portion 21 extending into the top of the backrest. The cross bars 19 are used for anchoring and forming purposes, andare positioned to provide surfaces which lie at or adjacent the plane ofthe seating surface (or at the base surface if cushions are used). Manymodifications of this structure are feasible, and will suggestthemselves to those skilled in the art. For example, the back cushionmay consist of a rectangular foam piece which sits upon a frame portionextending up to about the height of the seat, and which rests primarilyagainst a single piece board back. It will be appreciated that the armrest of the embodiment of the invention illustrated in FIGS. 1-3 is notextensively cushioned but may include padding material.

Since the joinders and assembly of the frame 10 are conventional, thereis no need to explain further details here. The frame is, however,configured to receive the marginal portions of the covers inparticularly advantageous fashion. The frame is constructed to providemarginal anchoring points along the sides and at the lower front andback edges, as well as along the juncture between the seat and backrest. In the exemplification of FIG. 1, these marginal anchor pointsextend along the under side of the back, along the rear side of the backrest, along the front sides of the back rest to the seat, along thecross bars at the arm rests, and along the sides of the seat to thefront underside of the seat. This arrangement is particularlyadvantageous, because elastic pull may be exerted on a cover in alldirections.

The cushioning material such as the seat v14 and the back rest 16 mayconsist for example of latex foam rubber, polyfoa-rn or the like.Preferably the cushioning consists of a material which is unitary, thatis, which will support itself and need not be held together by fabricsuch as is the case with kapok, animal hair, cotton felting and thelike.

In accordance with the present invention the seat and back rest of thefurniture are covered by a single piece of upholstery cover generallyindicated at 25. The fabric of the cover may consist of a conventionaldry-cleanable material, inasmuch as most current cover materialssuitable for upholstery use are made of this nature. Alternatively, itis readily feasible to utilize a fabric that can be washed. While suchfabrics are not now in general use they can be readily manufactured of amaterial, such as cotton, synthetic fibers and other materialsconstructed to have a heavy thread or weave to stand the wear and tearto which the fabric is subjected in use as an upholstery cover.

The upholstery cover 25 consists of a lower vertical front portion, ahorizontal seat portion, a generally vertical or inclined back portion,a horizontal top and a vertical back panel. Further, in accordance withthe present invention the marginal portions of the cover 25 areelastically coupled to the frame 10. T 0 this end the marginal portionssuch as the lower front margin 26, the rear margin 27 and the two sidemargins 28 and 30 are provided, for example, with a plurality of elasticloops 31 which may consist of rubber bands or similar elastic material.As illustrated in FIG. 3 the rubber loops 31 may be sewed as at 32 to afolded-over marginal portion 30 of the cover. The spacings between theelastic loops 31 are chosen relative to the stiffness of the cover 25material to provide uniform and wrinkle-free tensioning of the cover 25in the direction toward the margin. Alternatively, the fabric or cover25 may be provided with eyelets 33 through which the rubber loop 31extends as clearly illustrated in FIG. 4. It is also feasible to sew orotherwise attach as by seam welding a rubber or elastic strip or band 34to the fabric 25. As shown in FIG. 5 the rubber band or elastic strip 34may again be provided with eyelets 35 through which elastic loops mayextend.

These elastic loops 31 are secured directly to the frame 10 by suitablebent-over nails or hooks shown at 37. Preferably, as illustrated in FIG.3 the vertical frame panel 17 is provided with a semi-sphericaldepression in which the hook or nail 37 is disposed. This constructionis preferably used where the covering material is to fit fiush over thepoints as which the loops 31 are to be secured, or where the user of thefurniture may come into close proximity with the hooks 37. Thus thefront panel 17 and the upper vertical panel 20 may be provided with theprotected or hidden hooks 37 of FIG. 3. In other places such as thefront and back underside portions of the lower frame 11 unprotectedbent-over nails or hooks may be used, as shown.

Similarly covers may be used over each arm rest of the sofa. The cover45 primarily consists in one form.

of a single piece of fabric formed of a number of individual panelswhich may be sewn together. Thus the cover 45 includes a continuousstrip of the width of the arm rest and extends from a front marginalportion 47 upwards, horizontally over the arm rest, upwards across thetop and over the back to form a similar rear marginal portion, notshown. An outer panel 48 covers the outer sides of the arm rest while ashort panel is extended along the inner side of the arm rest, this panelterminating in a flap 50. Various marginal portions, such as the frontunderside edge 47, the flap 50 and the edge 51 at the under side of eachside panel are again provided with elastic loops 31 which are secured tosuitable hooks 37 on the frame. Note that the flap 5t) fits between thecross bars 19 in the side arm, being held by the anchored elastic loops31 to either of the cross bars 19, as desired.

The upholstery cover is attached to the frame 10 in the followingmanner, if the starting point is assumed to be the front underside. Atfirst the loops 31 on the lower marginal front portion 26 are secured tothe front underside of the frame 11. Subsequently the loops on the sideportions 28 and 30 are secured to the frame along the lower verticalportion and along the horizontal seat portion at the cross bars 19. Thenthe loops pro vided along the line of juncture of the seat and the backrest portion of the fabric are secured to hooks 37 along a verticalframe portion 52 (see FIG. 2) at this juncture line. Thereupon the sideportions 28 and 30 of the fabric are secured to the frame along the backrest and are finally coupled with the rear marginal portion 27 to therear underside of the frame 11. It should be noted that the fabric ispulled tightly over the back rest and the rear of the back rest as wellas in the side directions. As a result the fabric is pulled slightly offthe seat portion as illustrated in FIG. 2, thereby to improve itsappearance and to keep the fabric from being in touch with the seatcushion at all times. With other types of frame construction the elasticloops at the juncture line of the seat and back may be anchored to framepoints which are above the level of the seat fabric. Any tendency toadhere because of static electricity or other reasons is therebyeliminated.

The arm rest cover is now attached in a similar manner. First, the loopsalong the flap may be anchored to a cross bar 19. Then the entire cover45 may be pulled over the arm rest. Thereafter the front underside edge47 and the principal underside edge 51 are secured to the frame. Even ifthe arm rest cover 4-5 is not secured at the back underside, it is fullytautened and held and does not slip under hard use.

When the principal cover is thus secured it will present a neatappearance because the fabric is skin tight over the cushioning materialand the frame except that it is pulled slightly off the seat cushion 14.It will be appreciated that the fabric covers 25 and 45 may be removedas readily as they are were put on and do not require skilled labor toput them on or off. The anchoring points for the principal cover 25 arecompletely hidden by the side arm covers 45, and the anchoring pointsfor these covers 45 in turn are out of sight and possible contact.

The invention has been illustrated in conjunction with a straight linedesign, for which it is particularly suited. it is also fully amenableto use with other furniture styles, however. Thus, because the fabriccovers are tautened in all directions, detachable cover furniture inaccordance with the invention may be provided in traditional styles, andin modern curved line designs as well.

Furniture in accordance with the invention is thus characterized by thereadily detachability of the covering fabric, but also by the taut andfinished appearance of Well made fixed upholstery covers. The fabric isfirmly anchored to fixed frame points, but in such a way that anchoringpoints are hidden, while separate adjoining fabric pieces are so firmlyheld that they need not be sewn together.

Furniture in accordance with the invention is also characterized bygreat versatility. Of primary importance, of course, is the fact thatcovers may be removed for dry cleaning or washing, or for interchange ofstyles or colors, or because of damage. It is also now possible,however, to change arm styles as well, as is explained more fully below.

A modified but interchangeable construction of an arm rest isillustrated in FIG. 6 to which reference is now made. Here the arm restgenerally indicated at 55 is made of wood or similar structural materialand is not covered by fabric. The arm rest has a lower portion 56 whichfits snugly over the cover 25 and the seat and back rest cushioningmaterial. The arm rest has a horizontal raised part 57 which serves asthe arm rest proper. The entire arm rest 55 can be removed by moving itto the right in FIG. 6 and can be put back again by reversing theoperation. Snaps or elastic loops (not shown) may be used to fix the armrest 55 in position. It will be appreciated that the arm rest 55 coversup the elastic loops 31 and hooks 37 in the same manner as the previousexamples.

Another construction of an arm rest is shown in FIG. 7. Here the armrest 60 forms a small side table which may be provided with a lowersurface 61 to support books or other articles. Again the arm rest may bemade to slide sideways over the sofa so as to cover up the elastic loops31 and hooks 37. Alternatively, however, this arm rest 60 constructionmay also be fitted over the arm in furniture such as shown in FIG. 1.Whether or not the fabric is changed, there will be a virtually completechange in the appearance of the unit.

An upholstered arm rest construction is also readily feasible as shownin FIG. 8. Here the side arm cover 45 (viewed partly in section) extendsabout an arm rest which is formed of an initially loose polyfoam armrest cushion 64 resting on a frame cross bar 65. The side arm cover 45is secured to the underside of the cross bar 65 and along the bottomside margin 67 by elastic loops and hooks, to the underside of the frame11. The side margins of the principal cover 25 are also secured to theunderside of the cross bar 65. Since the entire height of the arm restis formed by the integral arm rest cushion 65 a very soft support isobtained which permits the user to rest comfortably against the arm rest65. This construction may be seen to provide another alternative for thearrangements of FIGS. 6 and 7.

Another upholstered arm rest is illustrated in FIGS. 9 and 10. Here aframe portion 70 supports a relatively smaller arm rest cushion 71 overwhich the fabric or cover 72 is stretched. The fabric is secured to thebottom frame 11 as shown at 73. This is preferably accomplished by meansof a Velcro tape or fastener. Velcro tape is sold in the trade underthis name and comprises two mating portions 74 and 75 shown in FIG. 10.One of the tapes, say tape '74, is secured to the cover 72 and consistsof a pile of material having thread-like loops having an appearance ofvelvet. The mating tape 75 is secured to frame 11 and also hasthread-like loops which, however, have been cut open. Hence the loops oftape 74 engage the open loops of tape 75 to form a tight but detachablebond. The tapes 74, 75 can be disengaged by pulling them apart like azipper. The cover 72 is similarly secured to frame 70 as shown at 76.The arm rest of FIG. 9 is less soft and of somewhat simplifiedconstruction.

Referring now to FIGS. 11-16 there is illustrated a davenport, couch orchaise longue convertible into a bed and constructed in accordance withthe invention. The davenport has a large seat which may be covered by asingle upholstery cover 81 extending over the seat cushion ing material82 supported by a frame 83. The marginal portions 84 and 85 of the cover81 may be secured to the frame 83 by elastic loops 31 and hooks 37 inthe manner previously explained. Two arm rests 86 may be provided forthe davenport and may be constructed in the manner previously explainedin connection with FIGS. 1-3 or 6-9. However, the arm rests 86 may alsobe omitted, if desired.

The back rest generally indicated at 87 is movable with respect to theseat 80 to form a bed when extended. The back rest 87 is held by twostrong decorative tapes 88 which are secured at 90 to the back rest andat 91 to the seat. The tapes 83 may be sewn to the seat and back rest orsecured in any other convenient manner. Each tape 88 extends around anedge of the back rest 87, and each is arranged to have a predeterminedlength. The back rest shown in FIG. 12 forms a davenport. When it isdesired to convert the furniture into a bed, the back rest is firstrotated through 90 as shown in FIG. 13 where it rests flush with thefront edge of the seat 80. Another rotation of the back rest 87 through180 causes it to assume the position of FIG. 14 and the bed is ready foruse.

It will be observed that the tape 88 holds the back rest in thepositions of FIGS. 12 and 14. However, when a person leans against theback rest, it may have a tendency to slide backwards. To prevent this asupport 92 may be provided in the arm rests 86. The support 92 may takethe form of a rod or leg that can be folded into a recess in the armrest as illustrated, for example, in FIG. 15 and can be extended as bestseen in FIG. 16 to support the back rest. Also legs 93 may be recessedinto the back rest and may be pulled out to support the back rest asshown in FIG. 14 when the davenport is converted into a bed.

There has thus been disclosed an upholstered article of furniture whichis provided with an upholstery cover which can be readily removed andreplaced without requiring skilled labor. Thus-it is possible to removethe cover for washing or dry cleaning, or the cover may be replaced byanother cover to change the color scheme or to replace a worn-out ordamaged cover. The upholstered furniture may be provided with an armrest having a cover that can be similarly removed or replaced.Alternatively, the arm rest may be uncovered and designed to hide theelastic coupling between the cover and the frame. By virtue of theelastic coupling between the cover and the frame the cover will alwaysbe skin-tight over the cushions and frame and will preserve its neatappearance.

The upholstered furniture of the invention may also take the form of adavenport or the like that can be converted into a bed. Again the covercan be readily removed for cleaning or replacement thereof.

The upholstered furniture of the invention preferably utilizes acushioning material of unitary construction such as latex foam rubber orpolyfoam. By this means it is possible for the cushion to retain itsshape without a cover so that the cover can be pulled over the cushionwithout the necessity of providing special means to hold the cushioningmaterial together giving it its proper shape.

While a number of alternatives have been suggested above, it will beappreciated that the invention is not limited thereto. Accordingly, theinvention should be considered to include all modifications andvariations falling Within the scope of the appended claims.

What is claimed is:

1. An upholstered article of furniture having a readily removable andreplaceable upholstery cover that remains tight and wellalignedcomprising a frame having a seat portion, and a back rest portion, withthe seat portion having a lower front portion, the sides of the frameproviding marginal anchor surfaces, cushioning material coupled to theseat and backrest portions of the frame, a single upholstery cover,consisting of a single sheet, for the article of furniture and extendingover the back of the back rest portion, the front of the back restportion, the seat portion, and the lower front portion of the seatportion, and having margins extending adjacent the marginal anchorsurfaces of the frame, elastic means detachably securing the upholsterycover to the frame along the sides thereof and at the bottom of thelower front portion and at the bottom of the back rest portion, and umcove-red detachable arm rest means adapted to slide over the side edgesof the frame so as to cover the elastic means therealong.

2. The invention as set forth in claim 1 above, wherein the elasticmeans extends along the underside of the lower front portion and theunderside of the back rest portion and wherein the sides of the frameare covered by said arm rest means throughout the seat and back restportrons.
